Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To contemplate efficient stress distribution by providing recesses in at least one part of an underlying insulating film of an Al wiring or an Al dummy wiring on the surface of a semiconductor chip. SOLUTION: Concaves 3 are provided on the surface of a base insulating film (SiO2 film) 1a at the end side of a metal wiring (e.g. Al wring or Al dummy wiring) 2 on the surface of a semiconductor chip 1, and an overcoat film 4 is formed on the top surface of the semiconductor chip 1. Because of that a material constituting the underlying insulating film 1a has higher hardness than a metal which constitutes the metal wiring 2, stress relaxation can be achieved efficiently. The shape, width, depth, and the number of the concaves 3, or distance from the position of the metal wiring 2, are not limited specifically. It is considered that a vertical shape with around 1.0 aspect ratio, a reverse taper shape with around 1.0 aspect ratio, a forward taper shape with around 1.0 aspect ratio, or a vertical shape with around 1.0 aspect ratio, are available.  However, a forward taper shape with lower aspect ratio is desirable to be used for blocking of an opening or prevention from sliding phenomenon of Al wiring.

Filed: 1988-11-16
Abstract: PURPOSE:To rapidly and accurately set an optimum measuring point by detecting variation in the power source current of a semiconductor device on the basis of an optically pumped current generated upon irradiation of the device with light. CONSTITUTION:When a semiconductor device 30 is irradiated with laser light which is switched ON, OFF at several tens of MHz by a modulator 42, an optically pumped current is generated at the timing of the laser light irradiation.

The movable part 7 is displaced in the direction shown by an arrow depending on the magnitude and direction of acceleration being applied thereto. A cathode 1c is integrated with the movable part 7 and a relative displacement takes place between the cathode 1c and a counter electrode, i.e., an anode 1a. The anode 1a extends along the direction of displacement' of cathode 1c and the electrode face thereof has such profile as the inter-electrode distance varies depending on the displacement (position). Consequently, the inter-electrode distance can be detected as the variation of current value.

Abstract: PURPOSE:To detect the abnormal temperature of a linear long material with a simple structure by providing a core part in which a thermosensitive color changing material changed to a color whose light absorption is easily changed to the light having a specified wavelength by a temperature rise is dispersed, and a clad part on the outer circumference of the core part. CONSTITUTION:An optical fiber 1 is formed out of a core part 1a in which a thermosensitive color changing material changed to a color whose light absorption is easily changed to a specified wavelength of the light from a light source by a temperature rise is included, a clad part 1b provided on the outer circumference of the core part 1a, and a sheath 1c provided on the outer circumference of the clad part 1b. When the temperature of the optical fiber 1 is raised by the temperature rise of a linear long material, the thermosensitive color changing material dispersed in the core part 1a is changed to the color whose light absorption is easily changed to the specified wavelength of the light from the light source. Since the degree of light absorption is thus changed when the light from the light source passes the core part 1a, compared with before color changing, the emitting light intensity of the optical fiber 1 is changed to change the light receipt signal of a light receiving part, and the abnormal temperature of the linear long material is detected from this change.
